Section 3 Introduction
Introducing lean production / rapid prototyping. NOT pre-production, production, post-production. Imagine these assets are for a bowling game. Knowing how fast / how many iterations to do. Knowing when to stop iterating! A Definition of Lean Production Eliminates waste created through overburden and unevenness in work loads. Maximises flow of value (anything that a customer would be willing to pay for). Maximises quality by discovering the 20% of gold. https://en.wikipedia.org/wiki/Lean_manufacturing The Pottery Fable Teacher challenges class. One half on quality, other on quantity. At the end of the term, which wins? Both from the quantity side. Moral… quality follows quantity.
Lean Production Pipeline

Hiding Un-Needed Objects.
Need to understand these for getting rendering right.
Looking at the two in isolation.
Combining them to see the effect.
Still using Blender Render.
Diffuse vs Specular Reflections
Both are types of reflection.
Diffuse is when Light scatters as it hits a surface.
Specular is direct reflection of the light to the viewer.
Materials are often a mix of the two.
Diffuse and Specular: Blender Render

Using An Image As A Texture
Introduce procedural textures. Apply some to the chequers on the board.
Using Procedural Textures
Better overall to make models using quads.
Explain what they are.
Whatever you use- it is being converted back to triangles in the background.
Watch out making things non planer…
(Unique Video Reference: 25_CS_CBC)
Quads Vs Triangles and Ngons
Only happens with quads and NGons. Rendering & Exporting always converts geometry into triangles.- Lose control over the rendering. You cannot always see this in the 3D window. Makes a huge difference with flat models and flat shading. Triangles and NGons If your model comes to a point you might need a triangle. When sub dividing part of you model you are likely to create an NGon elsewhere. You will break loops when doing this. Solutions Good mesh topology from the beginning. Be lean and check your model through. Turn on mesh analysis (not 100%). Manually make face(s) Planar again. Normal, SZZ0.
Non Planar Geometry
Learn about edge rings. How they help you manage your geometry. Definition: A series of edges which are not directly connected, but share faces.

Your Section 5 Assets
We are going to do many iterations though to the end, even though the lamp won't be built fully! Later on rendering times are likely to be longer that the last section. We'll be making and testing the Lamp as we go.
Blender Render is generally quick and you get a reasonable result quickly. - Uses CPU Only. Cycles is a physical based renderer is accurate but takes longer. It is designed for GPUs but runs fine on CPUs. Why Use Cycles? We are going to use Cycles, since we are modelling a lamp! The two are not cross compatible, no switching. You can use other Renderers too, if you have access to them. We won't be covering these. Render Time Difference I will be showing you 3 Clips of a 4 second bowling ball animation. Blender Render - 2 mins Basic Cycles Render - 15 mins Thorough Cycles Render - 4 hours! Your Machine Specs : CPU Lots of different machine specs- vary massively. More Cores and Higher Frequency CPU. You are unlikely to hit memory limits when using CPU Rendering. You cannot use CPU and GPU at the same time. Your Machine Specs: Graphics Card nVidia cards- any that support CUDA. AMD/ATi Cards - Support has started not complete. You may hit memory issues if using a GPU. If in doubt or having trouble switch to CPU rendering.
Cycles VS Blender Render
Cycles runs with AMD/ATi and nVidia Cards. Install the latest drivers for your GPU. If you do not have a dedicated nVidia graphics card you can skip the next few lectures.
Dedicated Graphics Cards
This Lecture is for Windows machines, please skip to the next lecture for a Mac Setup. Show you how to check for your driver version. Make sure you have the latest Version of Nvidia's Drivers for your computer.
Installing CUDA On Windows
Show you how to download nVidia's CUDA drivers. Check for updates - have to manually check for updates via system preferences once installed. Can install updates from system preferences in future.
Installing CUDA On A Mac
Optional, if you do not have a dedicated GPU, this lecture will not apply to you. You may find that your GPU is slower than your CPU at rendering. Your CPU is free to do other things…

Rendering A Small Area
Using curves makes it infinitely editable. Changing the bézier handle type. Generate a 3D object by defining curves.
Using Curves To Generate Geometry
Refresh our knowledge on this. Converting our curve object to a mesh object. We can then perform mesh operations on it. We can choose to delete the original curve data if we want to.
Creating Geometry From A Curve
Culling Unnecessary Geometry We kept the curve data so have two options: Remake our mesh object, from those curves. Fiddle about with the geometry itself. Which path to take? Both are OK- depends on stage of construction. We'll be altering the curve resolution AND the mesh! Tidy up the rest of our geometry.
Altering Curve Resolution
Use an existing face to create a new face. Separate immediately creating a new object. This allows us to match up parts of our model, even when they're not exact sizes.
Existing Geometry To Create New
Design a rough outline for the lamp.
Make it believable as an object.
I have chosen a simple and raw design.
Remember It can always be beautified later on.

Understand you need both.- The texture has to exist on something! See that Geometry is for detail and textures are for the illusion of detail. Realise that the appropriate combination of both is used to create models
Using Textures Vs. Geometry
Setup the Add-on that enables you to import images as planes. Be able to import an image into a scene. Realise this can be another way of importing reference material.
Importing Images As Planes
Learn how to embed images into the blend file, both individually and collectively. Understand this is essential when sharing a file with someone else. Can create bloat if the external data becomes obsolete. -Show you how to remove external data
Packing External Data
Look at the Nodes that are created for the textures. Learn about the different types of connection points and what the coloured dots are. Which ones can be connected together and what they would do.
Node Type Overview
Learn how to use cycle’s nodes to apply transparency to your image. Use groups for nodes for simplicity Use those node groups again on other materials.
Textures With Transparency
Import an image without a transparent layer.- No Alpha Channel. Understand that this is useful if you have no image editing software, no time to process a load of images, or just trying out images for your textures What is Alpha? If an image contains an alpha channel, each image pixel is represented has an value which specifies the opacity of that pixel. In alpha channels, 100% is opaque pixel and 0% is transparent pixel. Not the best way… Ideal to have a Solid coloured background, either 100% Black or 100% White to separate the image from the background. It would be best if your images are processed to include an alpha (transparency) channel RGBA.
Textures Without Transparency
Name your new texture layer. Turn back on the camera and lighting and the grass layer.
Testing The Grass
Learn about light paths and how there are critical when using transparency.
Light Path Render Settings

You will be able to create your own mapping, with these we can make the illusion of detail.
We’ll be constantly checking our model externally
This will be focused mainly on an interior environment.
Section 7 Introduction
Create assets to be exported straight into an external program, like a game engine.
Creating our own textures, and other maps from high detail models and apply them to a low poly version.
Focused on modelling the interior of the Gothic Church.
You can use this technique within Blender itself too for optimisation.
I am going to be testing my model externally as I go so you can appreciate the impact externally.
We’ll be looking at Level Of Detail, in detail.
I will be keeping my scene simple, primarily for teaching purposes!
I encourage you to add more detail, experiment and have fun. Wouldn’t the scene look much more interesting with a chess set in it…
Planning Your Project
An Overview of Source Control
The what and why of Version Control Systems
Choosing your Version Control System (VCS)
What files to include / exclude
Commit = save a local snapshot
Reset = roll-back to a previous state
Branch, Push and Large File Support later.
Popular Version Control Systems
Subversion / TortoiseSVN
Alienbrain (for art but of order $10,000)
Free software by Atlassian
Visual front-end for Git or Mercurial
Mac and PC but Mac version is a little ahead
Good when learning as easy to visualise.
Version Control 2
Understand that there is NO one way of setting up your filing system.
Have a personal style of filing, if you don’t like mine, use yours.
Talk with your ‘team’ you will form guidelines from your own needs.
In a Team environment you will have guidelines or discuss with colleagues.
Some other software might expect certain things to be stored and named in a certain way.
In a Team / larger project it is critical that you can find assets, materials, textures.
Naming files well will help you and others.
There are some naming conventions that we will use in this section.
In Blender Organisation.
We are going to be making a much more complex scene than any previously made.
Organise it as you go, not afterwards!
Use description names, cube, cube.001 etc is not helpful to anyone!
File Structure & Naming
Focus on representations of the right size and shape, but JUST Block work models.
This allows quick iteration of your models.
Remember higher detail ofter requires more processing time too!
LOD Numbers and Letters
LOD 0 often refers to the highest detail model sometimes called the base model.
To avoid confusion, we are going to use Letters!
A represents the lowest polygon model, with B,C,D etc increasing in detail.
Watch Your Time / LOD
LOD and time taken at usually directly proportional to one another.
When fleshing out a scene and prototyping you probably want quiet a few assets.
You can test models and your scene quickly.
LOD vs. Time Taken Example
A - B - C - D
200 - 2,000 - 20,000 - 200,000
30mins - 2 hours - 1 day - 1 Week
*Every polygon counts!
**Time includes other artwork too
Level Of Detail (LOD)
RH Triangle whose sides are 1,1,sqrt(2).
Square 1x1 and other Integer Rectangles.
Isosceles whose base is 1 and sides are 2.
Equilateral Triangles of side length 1.
These will all fit together well and consistently
NONE… at this stage.
Later it can feel restrictive.
That is where you want to be customising and adding detail, not in the early stages
Formulae In The Fields
You can type formulae into Blender’s fields.
We can use this to solve otherwise complicated measurements.
Setup Up Our Repository.
Learn how to exclude data from our repository.
Stage our files.
Make our first commit.
How Many Repositories?
You could use a repo per model that you create, this would give you the best level of control.
You could track your whole project in a repo.
It will depend on the complexity of your project and how much control you NEED.
Allow faster commits at a smaller size and keeps the database simple and manageable.
Avoid storing derived / generated data in the repository.
Example here: will be our reference material.
You’ll need to save all the documents that constitute that commit first.
Just like saving your working folder and zipping it up at that moment in time.
Setting Up Our Repo & Committing
Learn how to manage repetitive tasks.
Understand good uses for appending an Blend file into your scene.
Repetitive Tasks In Blender
Set your commit message before working
Start building your building.
Notice a few issues and work out a way around them.
Using Our Building Blocks
Learn about Datablocks.
Understand that knowing about them is about to become much more important.
We have come into contact with data blocks lots but let now go and explore them directly.
Must have unique names per type.
Can link to each other.
Can link across blend files.
Unused Datablocks are eventually removed.
This is Where we have used Fake Users in the past to preserve that particular datablock.
Sharing Datablocks Example
The same texture on many materials.
The same material on many meshes.
The same particle system and so on.
We will often share and then make the data block unique.
Introduction To Datablocks
Learn more about linking to another blend file.
Link an object datablock.
Understand that there is a datablock hierarchy.
Keep an eye out for when you might loose data.
Linking To An External Datablock
Learn more about linking datablocks.
Understand what is happening when you link.
Realising when you need to use a Proxy
Creates a New object, that is a parent of the linked data.
Allows transformation of an object.
Can now Scale, Move, Rotate etc.
Otherwise exactly the same as the linked file.
The object datablock is linked to original and any dependant datablocks.
Linking Blend Files- Making a Proxy
Learn why you want to make a linked datablock local.
Understand we are starting to sever links by doing this.
Learn about the various stages of making it local.
Decide when would be a good time to localise a datablock.
Advantages And Disadvantages
Advantage: You will have more local control.
External files moved, project can stay together.
Disadvantage: Potentially more work involved.
Any edits you make on the original affect all linked data blocks but not the ones made local.
When Do you Localise?
When the link is not required.
When you want to make the asset unique in this particular file.
When you want to make changes irrelevant to other potential projects.
Make Local: Option 1
Selected Objects: Clones the object Datablock to the new blend file.
All other datablocks remain linked to the original file.
This allows changing of anything in the object datablock.
Make Local: Option 2
Selected Objects and Data: Clones the object & data Datablock to the new blend file.
This allows editing of the mesh data, breaking that link and making it a local file.
The materials & other datablocks remain linked to the original object.
Make Local: Option 3
Selected Objects, Data and Materials: Clones the object, data and materials Datablock.
This allows editing of the object data & materials datablocks.
Breaks those links, making them local to this file.
Make Local: Option 4
All: As it sounds, this is pretty much the same as appending the object into the scene. It is now entirely local with no links to the original file.
Linking Blend Files: Making Local

Understand what a “profile modelling” is.
Potentially speed up modelling by mirroring.
Use a series of methods to produce a profile that we can use in our scene.
Future: Use the same profile in different ways
A profile is the outline you get when you view something from a particular angle.
Imagine slicing through your model.
Realise we have used them in the past: Lamp Base was produces with curves and the Pin was geometry based.
We’re going to bump up our extrude speed
We’re going to be using the bevel tool for construction and defining sharp edges.
A subsurface modifier for making the surface.
Profile Modelling By Extrusion
Create some alternative detail.
Convert Mesh objects into a Curve objects.
Use those 2 curves to create geometry, one controlling the profile, the other a path.
See this is great for more accurate path following.
Profile Modelling Using Curves
Use the Array modifier to repeat a mesh object the length of a curve.
Deform the array using the same curve data.
End up with some pretty awesome results!
Profile Modelling Using Mesh Objects
Learn how to use light portals.
Understand the limitations of their use.
See that they can dramatically increase quality given a fixed number of samples.
See they’re especially useful for indoor environments. lit by environmental lighting.
How Cycles Lighting Works
Light rays are fired out from the camera until they hit a light source.
With a Lamp Blender knows where the light source is so ONLY fires rays that will eventually hit the light source.
With an emissive material Blender doesn’t know where the light source is.
When the camera fires those rays, some of them will never reach a light source, this introduces more noise.
In an Interior with only windows letting light in. The rays bounce around a lot and only a few reach the light source. HDR/Environment lighting.
This introduces a lot of noise in the final image.
How Portals Help
Portals help by telling Blender where to aim those rays.
This produces much less noise in the final image.
Portals are a cycles lighting feature.
They increase light calculation time, however produce much much less noisy environments.
Portals only work with Environmental light. Using them otherwise can reduce image quality.
Have little impact if you put something in the way!
Go over how to extract a previous version of your files.
Become aware that Blender files that are made up of linked files need to be accessed and restored a different way.
Using Source Control- Resetting
No longer ask what does UV stand for?!
Overview the mapping in upcoming lectures
Understand that we will be creating these maps from scratch, and then using them again to speed up further workflow.
X,Y and Z are used for the Co-ordinates.
UV are like the ‘X’ and ‘Y’ co-ordinates of an image.
UV mapping is the process of projecting a 2D image to a 3D model's surface.
Introduction To UV Unwrapping
Understand more about unwrapping.
Be able to unwrap more complex models
Realise this is a great starting point for a lot of meshes.
See it gives a basic unwrap that we can work with.
A UV map, is a projection of a 3D mesh to 2D.
Whilst unwrapping is necessary to project an image
We can let blender ‘guess’ how to unwrap.
Unwrapping gives you control over how your model is mapped in 2D space.
Essential when using assets outside Blender.
Essential when using textures within Blender.
Necessary if you want control over how something looks.
Smart UV Project
How Is It Coming Together?
Do some organisation to our outliner before things get out of hand!
Get an “LOD_B” Mesh Object Ready to be Linked into our main scene.
Adding More Detail
Realise starting again is sometimes the best option.
See that even well prepared scenes can be broken by subtle changes.
Get help with problems you may have run into when making your building.
Realise sometimes Smart UV project is 99% of the way there but something is not quiet right.

Have a quick tour around my Church Vault.
See the challenges that we can have with more complex Models.
Troubleshoot some common unwrapping issues.
Work out ways to make an unwrap easier and quicker.
Complex Shapes & UV Mapping
Realise that UV unwraps will have seams in them.
Learn how to mark seams where you want them.
Understand that this gives us the most control over our models unwrap.
What Is A Seam?
It is a “cut” it your model, telling Blender how to unwrap your model.
It allows you to separate parts of your meshes.
Texture those parts individually.
Tips For Marking Seams
Seams can easily cause distortion and misalignment of textures.
Seams often occur on hard edges.
They are made where you are least likely to see them.
Understand that this gives us the most control over our model.
Introduction To Marking Seams
Create your own Image using Blender.
Become more familiar with the image editor.
Realise Blender’s limitations when it comes to image editing.
Understand you may have to use external packages for better control.
Painting In The Image Editor
Mid Section Quiz
The Diffuse Map
Create a hand painted texture in the UV image editor and apply it to your models!
Be creating the diffuse map from scratch
Explain what the diffuse map does.
What Is A Diffuse Map?
Is the most common map, and the one most people think of when someone says “texture”.
It defines the colour and patterns on a surface.
Can be challenging to imagine a surface without light source, or rather with uniform light
Avoid creating detail that would usually be generated by bumps on the surface.
We are going to avoid painting shadows too.
If done, this is called ‘baking’ into the image.
Learn how to use images to control your materials.
Understand why these control images are black and white.
Create a simple stage for our building.
Why Black and White?
These Greyscale images define “values” on a per pixel basis.
Black represents a value of 0 and white a value of 1.
You map them to your model like you would any other image.
Using Images For Control
Use a texture to control how light interacts with a surface.
See how to use a texture as a bump map in Blender Render.
Use Generated textures rather than hand made.
Normal and Height/Displacement maps are both types of bump maps.
We’re going to use a displacement map.
They tell a shader HOW to interact with light.
This gives the illusion of detail on a surface.
Can increase render speeds vs geometry.
Illusion of Detail- Using Bump Maps
Create real detail using a texture.
Use a displacement map to alter geometry.
Understand that you need geometry first to modify.
Use the displacement influence in Blender Render.
Then use the displacement modifier in a similar manner.
An Important Reality
They are not suited to things like generating a final brick wall. V High Poly count required.
They're very useful for applying detail e.g. scales on a lizard/fish or dragon.
Great for generating geometry and then optimising
For larger items, like terrain.
Using Displacement Maps
Understand they are a type of bump map.
Gain a greater understanding of how normals work.
They contain direction information not height information.
There are 4 Main Types
Create a normal map.
Understand when to create a normal map.
Use a process called baking.
See the baking is the fundamental process for creating other map types too in Blender.
Understand about cages and why they are used.

Applying A Normal Map In Blender
Understand that resolution will control the level of detail at a particular distance.Realise when a texture is too large or too small.Learn about the power of two (POT) and why and when it is important.Power Of TwoComputers work with 1s and 0s, or Binary.A lot of external programs need POT textures.They aren’t necessary in Blender but are a good standard to adhere too, especially when working with external programs.Don’t have to be ‘square’, providing side length is a POT.Which Numbers are Power of 2?Mathematically they’ll be 2 to the power of n or 2^n. eg. 2^5 = 32If you have been around computers for a while you’ll recognise this sequence: 2, 4, 8, 16, 32, 64, 128, 256, 512,1024, 2048, etc.Textures Of Different Sizes.Need their own UV Map.Probably not exportable due to multiple UV maps.Best to stick to one texture size for any given unwrap.Larger textures require more memory.What Size TexturesHow far away is the camera from the object/texture?How big is the object?What’s the “Retina” Texture level?rTexture = 3266 * Tan(Size/Distance)
Learn how to use the multi resolution modifier.See it is similar to the subsurf. modifier and great for multiple resolutions of a single model.Learn to control how sharp edges.Understand that this is best applied to a base mesh that is close to the ‘final’ low-poly version.

Just following along or without reference material will lead to frustration and a lot of wasted time.
Section 8 Reference Material
2 Objects can have the same shape, yet a different mesh construction.Use quads wherever possible. nGons and Triangles will cause pinching in your model.Topology can determine how easy it is to edit or animate an object.Topology defines a faces key shapes.Edge/Face loops will follow features.Loops will help with editing.Loops will help with deformation / animation.
Good Mesh Topology
Box Modelling: Building up the model from a primitive, adding detail as we go.Poly to Poly: Building up your model one polygon at a time.Sculpting and then Re-Topologising: Can be very time consuming
Possible Construction Methods
You have probably already done it to some degree.Remaking a mesh so that the arrangement of polygons is uniform and often all quads.Can significantly lower the polygon count.Planning can help avoid doing much of it.Start low LOD and working up can help avoid it too.It is time consuming.Do you Need to Retopologise?Almost always.Planning can help avoid it.If sculpting the original model it will be necessary.Leads to a clean and well defined mesh.Others can then work with your mesh too.It enables animation possibilities.Allows you to refine and easily edit your mesh.
Introduction To Retopology
You can Add Images as planes, this allows you to see the image all the time in the viewport.Adding images as background images will only show the images when looking Top/bottom, Left/Right, Front Back and in orthographic view.Create a base Mesh to start with and SaveAs when you reach a point where you can branch to make different models.
Creating The Base Mesh
Making notes on your model.Sketching and planning ideas.Roughing out ShapesConverted to edgesIt can be use to create 2D Animations

You'll learn how to use the knife tool.See that it gives you many opportunities to craft and re-craft your model.Understand that it can both ruin and fix your topology.
The Knife Tool
You'll learn how to use the Rip tool.You’ll learn how to use the Rip Fill tool too!Useful when you wish to add detail that otherwise would be difficult or time consuming to construct.
Rip and Rip Fill
You'll learn about edge and vertex sliding.See that it is a useful way of refining your model without having to create or remove existing geometry.
Vertex Slide and Edge Slide
You'll learn more about where poles are really useful.How to use a pole to terminate edge/face loops.How they can guide and redirect edge/face loops.Remember a edge/face loop doesn’t have to link back to itself.
Routing Face Loops Using Poles
Define the 5 main face groups that make up the face.Expect to make mistakes. Go with it and remember to Save often, and be prepared to start over from the base head.Create the Nose
Defining A Face's Main Face Loops
There aren’t any right settingsSkin is a complex surface.It has more than one tone.It’s shiny in some places, dry in othersSkin can be thin or thick letting some light through or blocking it all.
Getting The Right Skin Tone
My Scene Contains no direct lighting as of yet.Lighting can change the feel and look of a scene.A lot can be learnt from photo/videography.When using Cycles lighting should be setup as it would be in the real world for best results.3 point lighting is a common lighting method.3 Lights: Key Light, Fill Light and Backlight.
3 Point Lighting
Light penetrates the surface of an objectScattered in the materialSome light leaves the surface at a different point.The more distance the light travels before exiting, the more it will be absorbedThicker areas will absorb more than thinner ones.Most shaders we have used so far are direct surface scattering
This Quiz will test you knowledge of this section so far.
Mid Section Quiz
Usually used for controlling the weighting of shaders via the mix shader node.The Fresnel output has a very sharp fall off.The Facing output blends from one shader to the other more linearly.Both depend on the angle of incidence of the surface in relation to the viewer/camera.
The Layer Weight Node
Render Time PBR is necessary for creating anything realistic.Getting something looking like it does in the real world is critical to a lot of work.Cycles is almost there, but is misses a few pointsIt doesn’t calculate Fresnel automatically and roughness can be tweaked to be more useable.
Physics Based Rendering (PBR)
The ColorRamp node is used for mapping values to colours with the use of a gradient.It can be customised to produce interesting results.We will be using it to control a single value so can stick with Grey scale.Used to graphically control values.
The Color Ramp Node
Gain a better understanding of how light works in the real world and how that transfers into cycles.Look at 6 ways that light and surfaces interact.Gain some understanding about the physics behind how our materials are working.We’re not going to get too deep into the math behind it!
How Light Interacts With A Surface
Makes things more physically accurate.Everything has a fresnel effect in the real worldCycles doesn’t do it by default.Low Roughness > High amount of FresnelHigh Roughness > Low amount of Fresnel
The Fresnel Node
No longer will you have to keep making the same basic shaders again and again.You’ll learn how to start your own library of shaders and materials.Gives you the ability to continually improve your shaders and materials.
Reusing Shaders And Materials
We’ll use it to mix 2 colours together.See that it can be used to mix more that just colours together.It accepts 6 channels in through 2 colour inputs and 3 channels out- mixing together the 2 colour inputs together based up a Blend type and factor.
The MixRGB Node
Use this node to take control of an object's normals.You’ll see the vector coordinates we will observe are represented as WORLD Space normalsWe shall use this node to control the amount of fresnel based upon the amount of roughness.
The Geometry Node
We’ll get to grips with what Hue Saturation and Value mean.A HSV Value is a cylindrical representation of a point in RGB colour space.Hue simply means colour/shade.Saturation is how much there is of that colour.Value can be considered like brightness.
Hue Saturation Value (HSV)
We’re getting back to modelling.We cannot fully texture our model until the modelling stage is complete.We’ll take a look at the ear. - With all the folds it can be a challenge!There are 2 main loops for the ear, the inner and outer one.We’re going to make it separately in order to focus on the model.Isolation can be a good and bad thing.
Making Objects Separately
We will join the 2 meshes together forming one mesh objectThere is more than one way to do this.It is likely to involve some re-topology.
Joining Separate Objects
We’ll see that detail can be added in various waysUse the multiresolution modifier to create derived data.Sculpt the rest of the facial detail we need.
Manually move the vertices about.Add more vertices (ill advised)An accomplished artist could potentially paint the detail straight away.
Adding Detail with Sculpting
Think about your seams.Try and leave the face intact -without seams.Discover any parts that need their own island

Welcome to Destruction
This may be all you need if you want something quick.It can be used as a starting point.We’ll explore what it is actually doing for us.
Simulate the real world.You can manually place every bit of destroyed or deformed geometry if you wanted to.Enables you to create a complex scene easily and quickly.Great for realism, shattering glass, falling towers.We will start with something simple.Rigid Body PhysicsSimulates the physics of solid bodies.Works closely with the Animation system.It will move and rotate objectsIt will not deform them.
Introduction To Blender Physics
Physics properties are not linked to the object or data datablock.
They are part of the Scene Datablock.
You cannot make links to the physics.
You can however, copy from an active mesh object.
(Unique Video Reference: 5_DD_CBC)
Copying Physics Properties
Wherever the ORIGIN is.You have control of this which isn’t always a good thing.This can lead to some strange results.Blender can calculate the centre of mass (assuming a uniform density)
Centre Of Mass
Remember: Blender allows you to animate almost anything.We can use this to toggle whether we are in control of, or the physics engine is in charge of our mesh.Blenders Physics Engine will remember what has just happened in the animation.Quick peek at the graph editor
Animating With Physics
Unfortunately Blender needs to be told HOW to break something up.There are a couple of ways of doing that:Manually- The most time consuming, not advised.Otherwise:- Generally using a particle system.Physics can then be applied to the pieces OR the particle systemThe way that particles are affected by physics is controlled in the particle system tab.The Mesh itself doesn’t have to have physics.Other objects that interact with the particles no need physics.Look at Particle settings.Look at the collision physics Data.
